Aluminium oxides or aluminum oxides are a group of inorganic compounds with formulas including aluminium (Al) and oxygen (O). Aluminium(I) oxide (Al 2 O)
Aluminium oxide (or aluminium(III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3.It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium oxide.
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
Aluminium antimonide – AlSb [4] [5]; Aluminium arsenate – AlAsO 4 [6]; Aluminium arsenide – AlAs [7] [8]; Aluminium diboride – AlB 2 [9] [10]; Aluminium bromide – AlBr 3 [11]; Aluminium carbide – Al 4 C 3 [12]
Amphiprotism is exhibited by compounds with both Brønsted acidic and basic properties. [3] A prime example is H 2 O. Amphiprotic molecules can either donate or accept a proton ( H + ). Amino acids (and proteins ) are amphiprotic molecules because of their amine ( −NH 2 ) and carboxylic acid ( −COOH ) groups.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
A variety of compounds of empirical formula AlR 3 and AlR 1.5 Cl 1.5 exist. [22] The aluminium trialkyls and triaryls are reactive, volatile, and colorless liquids or low-melting solids. They catch fire spontaneously in air and react with water, thus necessitating precautions when handling them.
Ammonium is a modified form of ammonia that has an extra hydrogen atom. It is a positively charged molecular ion with the chemical formula NH + 4 or [NH 4] +.It is formed by the addition of a proton (a hydrogen nucleus) to ammonia (NH 3).
